Patent DE-2402327-A1 (DE)
Title: Clamp for papers with U-shaped profile - has curved shank curvature radius smaller than radius of ball
Inventor: WILBS ALFRED
IPC: A47B97/02
Filed: 1974-01-18
Abstract: The clamp consists of a U-shaped profile with front and rear shanks converging toward the shank ends, and with one of them curved in cross section such that its spacing from the opposed plane shank at the side edges is smaller than in the middle region. A ball is received between the two shanks, and has a dia. larger than the maximum shank spacing both at edges and side edges, but smaller than the max. mid-region shank spacing. The radius of curvature of the curved shank in the longitudinal middle of the shank is smaller than half the dia. of the ball in the clamping region. The ball in the clamp position of the clamp unit, in which the shank ends face downward, has a triple contact with the two shanks.

Title: Support for printing cylindrical bodies - comprises diabolo-shaped rolls to support body at end edges only
Inventor: STANEK FRANZ
IPC: B41F17/22
Filed: 1974-03-29
Abstract: The support is designed especially for automatic pointing of cylindrical electrical components, e.g. small diameter capacitors, which have connecting wires emerging from their end faces. Two diabolo-shaped rolls are used to support the component and by virtue of their waisted shape the rolls support the components at its end edges only. This avoids the smudging of ink during the printing process during which the component is fed to the rolls and is raised by them into contact with a printing roll for the transfer of print onto the cylindrical surface of the component. The whole of the surface can be printed by this method.
Patent DE-2435606-A1 (DE)
Title: Linear integrated impedance with depletion MOSFETs - uses drawn-source series with each FET gate coupled to its drain or source
Inventor: REINER ROBERT DIPL ING
IPC: H01L27/088
Filed: 1974-07-24
Abstract: The linear integrated impedance consists of a chain of depletion type MOSFets. The MOSFETs are coupled together in drain-source series. The gate of each MOSFET in the series chain is connected directly to its own source or drain. If two series-coupled MOSFETs alone are used, their two gates are connected directly to their junction point. The advantage of using depletion type MOSFETs with their gates coupled to their sources or drains, as compared to enriched-type MOSFETs, is that the impedance of the transistors depends only on the source-substrate voltage, thereby allowing a more linear impedance to be constructed over a larger range.

Patent DE-2440125-A1 (DE)
Title: System for private intercommunication network - has circuit for monitoring number of transmitters connected in parallel to collective speech lines
Inventor: JOCHUM FRIEDBERT
IPC: H04Q3/62
Filed: 1974-08-21
Abstract: The transmitters pass a test potential through engagement marking contacts to a common evaluation device which, when the number of connected transmitters exceeds a permitted number, prevents their further connection. The transmitters (UE1) transmit the test potential without insertion of specifically testing switching means directly to the pickup windings of coupling relays (K1), which are allocated to them. The monitoring apparatus thus prevents overloading of the system, and several subscribers may be connected together in conference provided the maximum permitted number is not exceeded. The system is entirely automatic in operation and follows a well defined series of programming steps.

Title: Position fixing system for electromagnetic source - uses spaced direction finders supplying respective values to central control
Inventor: WAGENLEHNER HASSO
IPC: G01S5/00
Filed: 1975-05-03
Abstract: The position fixing system for an electromagnetic source uses a pair of direction finders and one or more central control points, controlling both at the same frequency and using the information provided by each to locate the source. The momentary values provided by the direction finders are stored together with a time reference before being processed in response to a command provided from the central control point, to obtain the average over a given time interval. The obtained valve is then fed to the central control point. Pref. the direction finders operate at several common frequencies in a cylic sequence under control of the central point.

Title: Pressure maintaining system for district heating network - adapting pump output to varying requirements of network
Inventor: SCHULTE-BONSFELD KLAUS ING GRA
IPC: F24D3/06
Filed: 1975-05-15
Abstract: Pressure-maintainings system for municipal heating network comprises an overflow valve (4), and a pressure-controlling pump (1) of which the speed is controlled according to the water stream supplied via the overflow valve, pref. so that the water stream takes on a low value just sufficient for discharge of a control pulse.

The surface formed can be supported by simple clamps which hook over the bent edges and are attached to T-sections beams (11) overlying the ceiling surface. The clamps are bent pieces of wire which clip over the T-flangs (13). When the strips are used to build a wall, metal plates with edges bent to correspond to the strip edges are used as fasteners. These are clamped at regular intervals along a wooden backing beam and the strips are clipped over them.

Title: Dyeing-printing synthetic pile textiles to simulate animal skins - in two dyeing-printing steps using cationic dyes
Inventor: FENNEKELS PETER
IPC: D06P3/76

Title: Tuning control for checking data transmission rate - adds synchronising signal digitally to data signals to produce DC signal if rate changes
Inventor: PAETSCH WERNDER
IPC: H04L27/16
Filed: 1975-09-17
Abstract: A receiver circuit ensures that pulse code modulated data is sampled at the correct rate. The synchronising signal is digitally added to the information signal to generate a DC signal that indicates any variation in transmission frequency. The receiver sends signals via a demodulator a synchronising circuit, and tuning circuit to a data output. The tuning circuit consists of a modulo 2 binary adder that sums the information signals with a synchronising signal, chosen to have a frequency twice that of the data transmission rate. Ideally the synchronising signals occur in the middle of the data and provide a null DC signal. If the frequency of data transmission changes, a positive or negative DC signal appears.

Title: Flue gas purifier mounted on chimney - comprises superimposed units giving easy access and filter changing
Inventor: LEINDL ANTON FRIEDRICH
IPC: F23J13/00
Filed: 1975-11-06
Abstract: Appts. comprises (successively in the direction of flow) a flue gas brake for pptg. solid particles, a pre-chamber with flap valve-controlled flue gas outlet in the walls, an absorbing filter for noxious substances and an exhauster. The entire chimney-mounted installation consists of component units one upon the other. The lowest unit is a pre-chamber with removable lateral walls, one pair of these walls (pref. opposite each other) having openings closed by flap valves. The central unit si a filter box comprising one push-in filter unit(s) which can be changed through the side wall. The top unit is a hood contg. the exhauster and an actuating unit for operating the flap valves. This actuating unit pref. is a low voltage generator which, when the exhauster is in operation, keeps the flaps shut but, if the exhauster fails, opens them to permit escape of the flue gases. Each of the three units is pref. a frame structure clad with panels and fitted with flanges for connecting to the other units. By arranging the openings in the lowest unit opposite to each other, there is no risk in a high wind of flue gases being driven back down the chimney, should the flap valves be opened. The filters are easily removed. Easy access to the chimney is available.

Title: Transfer fixture for locating self adhesive label - transfers label from dispenser sheet onto cardboard located on horizontally movable plate
Inventor: HEIMANN EGON
IPC: B65C1/02
Filed: 1976-03-27
Abstract: The manually operated fixture is used to transfer self-adhesive labels (36) from a dispenser sheet (40') onto a cardboard or paper sheet (B). The fixture has a horizontal locating beam (15) above which a curved leaf spring (28) forms a small slot through which the dispenser sheet is pushed. The sheet which receives the label is located on a horizontally movable plate. When the label (36) and the sheet (B) are in the correct relative position, a pusher bracket, which is part of a leaf spring, presses the two sheets together. This transfers the label from the carrier sheet onto the receiver sheet.
